Schedule: C++       92/05
========

- language supported: 3.0 without templates, error handling

- schedule:

    SD92 -- need to be able to show something

    March 1, 1992  -- finish coding and start shake-down

    March 15,1992  -- finish Beta documentation

    - ship alpha to treasured customers for preliminary evaluation ASAP

    May 1, 1992    -- start serious internal use at WATCOM (CSG?)

    June 1, 1992   -- start Beta test for first shipment type

    July 15, 1992  -- finish documentation

    Oct. 1, 1992   -- first customer ship

Left to do:    compiler implementation
==========

(1) long double
    -----------
    - awaiting codegen support
    - should work with minor effort (3 line change!)

(2) linker support
    --------------
    - a - Jim Randall now working on it

(3) CodeGen Support
    ---------------

(4) Pragma support
    --------------
    - a - need support for language linkages
    - b - make warnings levels different or as errors
    - c - extended information during compilation
    - d - need support for class generation
        - public, extern, local
        - virtual base threshhold (?)
    - e - re-implement traditional C pragma support (commented out)

(5) Message Support
    ---------------
    - need extra message information
    - need to react to pragma requesting extra information

(6) Data
    ----

(7) Expressions
    -----------
    - d - additional support for ==, != (member pointers)
    - f - support ->*, .*
    - g - support :>

(8) Function Support
    ----------------

(9)Operational Support
    -------------------
    - a - review options and upgrade
    - b - implement profile file for options

(10)Error Handling
    --------------

(11)Templates
    ---------

(12)Asm Support
    -----------
    - Fred has it in C; we can likely get it easily

(13)Declarations
    ------------
    - templates
    - exception handling - statement parsing
    - parser ambiguity resolution

(14)OverLoading
    -----------

(15)Debugging
    ---------
    - should be just code-generation work

(16)C header Files
    --------------
    - need to be edited to add extern "C" { }


Dependencies on others
======================

- 1 - long double: code generation required
- 2 - linker support


Time Estimates
==============
 item    time       who job

- 1    - 2 min.s    - JW - long double: 2 minutes
- 4(b) - 2 days     -    - #pragma support for warning levels
- 4(c) - 1 week     -    - extended information listed during compilation
- 4(d) - 1 day      -    - #pragma support for class generation
- 4(e) - 1 week     -    - re-implement traditional C pragma support
- 7(d) -            - -- - covered in 7(f)
- 7(f) - 3 days     - JW - support for ->*, .*
- 9(a) - 2 days     -    - review and fix up command-line options
- 9(b) - 2 days     -    - profile file for options
- 10   - 3 days     - JW - error handling
- 11   - 1 week     - AS - templates
- 14(e)- 3 days     - JW - need to fill out the special functions in Chapter 13
- 15   - 1 week     -    - add debugging support
- 16   - 1 day      -    - edit C header files
